PMBP是铀、钍、稀土的良好萃取剂。本文测定了铀、钍和13个镧系元素的PMBP固体络合物的红外光谱。发现金属离子除了对O—M—O键的振动频率产生直接作用,还对C=O键的反对称和对称伸缩振动频率及苯基C=C对称伸缩振动、C—H键面内弯曲振动频率等产生可觉察到的影响,并试以公式加以阐明。 PMBP is uranium, thorium, rare earth good extractant. In this paper, the infrared spectra of PMBP solid complexes of uranium, thorium and 13 lanthanides were determined. In addition to the direct effect of the metal ion on the vibrational frequency of the O-M-O bond, the asymmetric and symmetric stretching vibrational frequencies of the C═O bond and the symmetrical stretching vibration of phenyl C═C, the bending vibration of C-H bond plane Frequency, etc. have a perceptible impact, and try to elucidate the formula.
